This hose coupling of Pittsburg, in the county of Allegheny member is screwed upon the externally and State of Pennsylvania, have invented a screw-threaded portion 3 at the rear of the 5 new and useful Improvement in Turbines, casing casting, and is preferably of the same of which the following is a full, clear, and external diameter as the shell of thiscasing.
